Testing of winter drying defects on eucalyptus camaldulensis dehnh. sawn-boards

الملخص EN

The possibility of using Eucalyptus camaldulensis Dehnh.

as sawn wood was investigated by felling 12 trees and sawing the main stem into 3 thicknesses boards.

Three methods of drying were applied ( Kiln, Solar, and air drying) in winter.

The effect of girdling the standing tree was tested too.

Drying defects were examined and boards accordingly were qualified.

Results showed that drying method and board thickness affected each of end split, mean MC%, MG% and casehardening.

While bow was affected by the method of drying, collapse and twist were mainly influenced by board thickness.

Girdling showed no significant effects supporting its application as improving procedure.

Degrees of drying defects assured the validity of winter drying procedures for producing merchantable quality sawn-boards from the studied species.
